"The mongoose is any member of the Herpestidae family of small, cat-like carnivores".

Some species of mongoose can be easily domesticated. They are fairly intelligent and can be taught simple tricks, so they are often kept as pets to protect the home from vermin. However, they can be more destructive than desired; when imported into the West Indies for the purpose of killing rats, they destroyed most of the small, ground-based fauna. Because of this, it is illegal to import mongooses into the United States.
